My fuel gauge randomly stopped working. I changed the sender and checked resistance to the tipm and its where it needs to be. I calibrate the gauges using the trip Meter reset button and the gauge works and calibrates fine. I also took the truck to the dealer and got the tipm reflashed to see if there was an update on software and that did nothing. I don't know where to turn now. It is a 5.9l 07 so anything that I purchase from a wrecker or salvage is VERY hard to find as the parts are specific for the 6 month period before they swith ed to the 6.7l. Someone please help!
